<p>A multi-mode cavity filter, including a first dielectric resonator body incorporating a piece of dielectric material having a shape to support a first resonant mode and a second substantially degenerate resonant mode and at least a second dielectric resonator body incorporating a piece of dielectric material having a shape to support a first resonant mode; a layer of conductive material in contact with and covering the first the dielectric resonator body and the second dielectric resonator body; a first aperture in the layer covering the first dielectric resonator body and a second aperture in the layer covering the second dielectric resonator body, one connecting path(s) arranged to couple signals via the first aperture from the first dielectric resonator body to the second dielectric resonator body via the second aperture, for the purpose of creating or influencing a location of a zero or null in a filter characteristic.</p> |
